I've got a rookie question. I've been playing with it for a while today and can't get it to work. I'm trying to put together a script that matches a regex against a flat file that contains all our switches' names.

In the foreach loop, it prints off the expected results (the names that match $hostregex) and until I added the

my @version = $session->cmd('show version  ');

line, it appeared to go to the switch in question.

When I added

 my @version = $session->cmd('show version  ');

I get the following error: 

myname@bast1:~/bin$ testloop 101a
Global symbol "$session" requires explicit package name at /home/mynam
+e/bin/testloop line 31.
Execution of /home/myname/bin/testloop aborted due to compilation erro
+rs.
myname@bast1:~/bin$

Here's the script. Any help would really be appreciated. 

#!/usr/bin/perl
use Net::Telnet::Cisco ;
use strict; #always and forever, amen.
use warnings;  #or else.
use lib '/home/myname/bin/lib';
use subs ;

if ($#ARGV != 0) {
    print "usage: enter the switchname \n";
    exit;
}
my $hostregex = $ARGV[0] ;

my $infile = "/home/myname/zen/zen_devices_out" ;
        # print "You're using: '$infile'\n\n" ;
        open INF , "$infile" or die $! ;
        my @lines = <INF> ;
        my @matches =  (grep(/$hostregex/i,@lines)) ;

foreach (@matches)
        {
        chomp($_) ;
        print "'$_'\n" ;
        my ( $p1 , $p2 )  = get_p() ;
        my $session = Net::Telnet::Cisco->new(Host => $_);
        $session->login('myname', $p1);
            if ($session->enable($p2) ) { } else { warn "Can't enable:
+ " . $session->errmsg; } }
   my @version = $session->cmd('show version  ');
        print @version ;
  exit ;
